$PECIPICATION forming part of Letters Patent No. 366,453, dated July 1 2, 1887.

(No model.)

To all whom, it may concern.-

Be it known that I, EDWARD H. BROWN, of Bayonne, in the county of Hudson and State of New Jersey, have invented anew and Improved Door-Oloser, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation of a door havingmy invention applied thereto, the full lines showing the position of the parts when the door is closed, the dotted lines the position of the parts when the door is opened. Fig. 2 is a sectional plan view taken on the line a; x of Fig. 1, showing the door closed; and Fig. 3 is a similar section showing the door partially opened.

The invention will first be described in con nection with thedrawings, and then pointed out in the claims.

To the inside of the door Ais secured, upon the pivot to, the lever B, which is by preference in the form of an angle, and its horizontal arm is provided with the weight 0. Connected to the angle of the lever Bis the rod D, which is pivoted to the short link E, which is attached to the door-frame A by the block b and pivot c. The vertical member of the lever B is extended below the pivot a, as shown at (Z, to strike the lower end, f, of the checkweight F, pivoted to the door, adjacent to the lever B, upon the pin e, as shown clearly in Fig. 1.

The action is as follows: In opening the door the rod D and pivoted link E act to swing the lever B and weight O upward to the position shown in dotted lines in Fig. 1. The weight 0 in this elevated position reacts through the lever, rod, and link, and tends to swing the door closed, and will do so as soon as the door is released. The swinging movement of the lever B moves the projection (1 toward the hinged edge of the door, whereupon the weight F will swing toward the outer edge of the door until it strikes the stop-pin g. The weight F is considerably lighter than the weight 0, and only serves to prevent the door from slamming, for as the weight 0 drops from the position shown in dotted lines to that shown in full lines the end (Z of the lever B strikes the pointf of the weight F, so that this weight retards the descent of the weight G, and thus causes the door to be checked and closed without slamming.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The lever B, pivoted to the door and provided with a weight arranged at one side of the pivot, in combination with the rod D, pivoted to the lever above its pivot, and the link E, hinged to the door-post and pivoted to the rod D adjacent to the door-post, substantially as described.

2. The bent lever B, pivoted to the door, formed with the projection d and provided with the Weight G, in combination Withthe rod D, link E, attached to the door-post,and the weight F, formed with the projectionfand pivoted to the door adjacent, to the lever B, substan tially as and for the purposes set forth.
